To all whom it may concern:

Be it known that I, THOMAS G. BRAWLEY, a citizen of the United States, residing at Arcanum, in the county of Darke and State of Ohio, have invented a new and useful Attachment for Corrugated Roofing, of which the following is a specification.

This invention relates to roofings embodying corrugated sheet metalcovering.

It is customary to overlap several of the corrugations of adjoining sheets inan attempt to exclude the water from the base or support for the sheeting to prevent leakage and the objections accruing therefrom, and in some cases special sheeting is provided wherein the overlapping corrugations are of special design thus rendering the sheeting variable and more expensive 1n the manufacture thereof. In the former case, only a partial prevention of leakage is attained anddue to condensation, capillary action and siphonic action a certain amount of water will find its way to the base or support through the joints. In the latter case, although the efiiciency is somewhat better, the sheeting is of larger expense in the manufacture thereof, and also requires a uniformity in laying same thereby increasing the costo'f labor in applying the sheeting to the roof as well as raising other objections. A number of methods have been devised forthis purpose but have met with more or less objection in each case.

It is therefore the object of the present invention to provide an attachment for corrugated covering or roofingg, primarily for the prevention of leakag This invention contemplates the usage of sheeting of uniform corrugation which is the less expensive to manufacture and the necessity of only overlapping a single, corrugation at the adjoining edges of the sheets thereby increasing the area covered by each sheet as well rendering the sheeting rapidly and conveniently applicable to the roof to decrease the cost of the roofing for a given area surface and labor in laying same.

The attachment comprises a channel or laid on the base or support beneath the edge of, the lower or inner corrugation of the overlapping corrugations to catch the water or moisture creeping-through the joint and havin the flanges thereof of length to bring the e ges against the respective overlapped corrugations to brace the same, whereby upon nails or other securing members being passed through the overlapped corrugation to engage the base, the corrugations are prevented from being hammered downward or otherwise distorted.

The invention is illustrated in the accompanying draw ng, wherein similar reference characters indicate similar parts, and wherem- Figure 1 a fragmental' portion of a roof in perspective showing the present invent1on applied thereto. Fig. 2 is an elevation thereof. Fig. 3 is a plan view of a pair of channels or gutters used in carrying out the present lnvention, parts broken away.

Referring to the drawing in detail. the base or support of the roof is designated bv the numeral 8, the same being of usual boarding or the like, and the adjoinin sheets of covering are designated by of;

numerals 10 andll having the overlapped corrugations 12 and 13 respectively.

The channel is designated by the numeral 4, being formed from sheet metal, and the flanges 5 and 6 thereof are of different lengths. This channel 4 is laid upon the base or support 8 and under the edge of the lnner corrugation 13, the flange 5 extending upward to bring the edge against the intermediate portion of the corrugation 13 and the flange 6 extends upward to bring the edge thereof against the corrugation 12. The channel 4 may be secured to the base or support 8 by means of screws 9 or other securlng means, although the same is not absolutely necessary. After the sheeting and channel are laid upon the base or support, nails or other securing members 7 are passed through the overlapped corrugations 12 and 13 ad acent the channel 4 to be driven into or engaged to the base 8 to lock the sheeting upon the base. i

Where the joint of the corrugated sheetng 1s 'of considerable length, a number of channels may be laid thereunder by fitting the end of one into the end of the other as shown in Figs. 1 and 3 wherein the end of the upper channel or gutter 4 fits into the end of the lower channel or gutter 4, thus mak1ng a continuous channel or gutter in attachment as described, the ordinary cortheroof into the eaves trough, if the eaves troughis employed. The flanges 5 and 6 of the channel 4 in engaging the respective overlapped corrugations brace the same from being hammered downward upon the nails or other securing members 7 being driven into the base or support 8. It willv therefore be seen that the moisture or Water creeping through the joints of the overlapped sheets of the roof will be conveyed from the base or support by the channel 4 to prevent the base or support of the roof from leaking and by the provision of the rugated sheeting of uniform corrugations may be employed with the necessity of only overlapping a single corrugation at the ad-- joining edges thereof.

The channels or gutters may be manufactured at a small expense and thereby reduceto a minimum the cost of material and labor in a production of a roof of this character for the prevention of leakage through under the edge of the inner corrugation and having the flanges of lengths to bring the edges against the respective overlapped corrugations to brace same, and securing members passed through the overlapped corrugations to engage the base, as and for the purpose specified,

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
